Went to take the 69 Dart to a car show today. NOPE

I’d be really surprised if that was just an ethanol problem.

I run pretty much nothing but fuel from the no-name, economy price gas station on the corner. And it’s California, so it’s always ethanol fuel, and has been for a long time. I’ve never had carb issues because of it other than a few gaskets that dissolved before they started making them ethanol resistant and my original tank looks fine inside. So did the spectra replacement that was in my Challenger forever too.

All tanks are vented, so it’s not like you can do anything about that. I get that Florida is practically underwater already and the humidity is very different there. But I think something else was going on there. That sender looks like it was underwater, not just in fuel that absorbed some water from the air.

Also, if you’re storing it with less than a full tank that causes condensation to form regardless of the ethanol in the fuel. A full tank doesn’t have the airspace to allow condensation to form.

Or you could just drive it.
